Davey, P., 2009: An immigrant species observed most often in the southern-most counties of England and Wales, extending inland to central England and very occasionally on the west coast of Scotland, the larva feeding on various grass species. In Dorset, the moth was first recorded at Church Knowle by Reverend E Bankes on 12 October 1891. More recently, it has appeared in almost every season in the past twenty-seven years, and over that time it has been recorded in each month of the year. Annual frequency has varied from occasional to common with the highest numbers in coastal areas, but also occasional records from localities well inland. Records suggest that many White-specks are primary immigrants from abroad. The largest single peaks in 1977, 1989, 1990, 2000 and spectacularly in 2003 occurred on dates when the airflow was direct from Iberia and beyond. It may also be a transitory resident in favourable seasons on coastal grassland, for example between early September and early December at West Bexington in 2000, the moth was trapped on more than fifty per cent of the nights at a rate of two per night, suggesting a transient resident population that year.
